Insights
Excess adiposity is a global health issue. Between 2008 and 2018, Polish preschool children showed lower overall body fat but increased central fat distribution, raising metabolic and cardiovascular disease risks.
Area of Science:
- Pediatric Health
- Public Health
- Body Composition Analysis
Background:
- Excess adiposity presents a significant global public health challenge.
- Changes in living conditions contribute to rising obesity rates worldwide.
- Understanding pediatric body fat distribution is crucial for long-term health outcomes.
Purpose of the Study:
- To evaluate shifts in body fat ratio among Polish preschool children (3-7 years) from 2008 to 2018.
- To analyze changes in skinfold thickness and adiposity indices over a decade.
- To identify trends in fat distribution (central vs. peripheral) in young children.
Main Methods:
- Two cross-sectional studies conducted in 2008 and 2018 in Kraków, Poland.
- Measurement of skinfold thicknesses (triceps, calf, subscapular, abdominal, suprailiac).
- Calculation of adiposity using Slaughter's equations, trunk adiposity index, and limbs-to-trunk fat ratio.
- Statistical analysis using two-way ANOVA and Tukey's tests.
Main Results:
- The 2008 cohort exhibited greater lower-limb adiposity compared to the 2018 cohort.
- The 2018 cohort displayed increased trunk adiposity and a higher tendency for central fat allocation.
- Despite lower overall adiposity in 2018, a concerning shift towards central fat distribution was observed.
Conclusions:
- Preschool children in Poland experienced a decade of changing body fat composition.
- Increased central adiposity, even with lower overall body fat, is a negative trend.
- This central fat distribution pattern in children is linked to elevated risks for metabolic and cardiovascular diseases.
Abstract:
In the light of changes in the living conditions of populations, excess adiposity is currently a serious public health problem worldwide. The aim of this study was to assess the changes in the body fat ratio among preschool children aged 3-7 years from Kraków, Poland, between 2008 and 2018. The study group consisted of children examined in two cross-sectional studies. Analysed characteristics included triceps, calf, subscapular, abdominal and suprailiac skinfold thicknesses, and adiposity calculated according to Slaughter's equations. The trunk adiposity index and limbs-to-trunk fat ratio were also calculated. Statistical significance was obtained using two-way ANOVA and Tukey's tests. Lower-limb adiposity was largest in the 2008 cohort and trunk adiposity was greater in the 2018 cohort. The mean values of the trunk adiposity index and limbs-to-trunk fat ratio were lower in the 2018 cohort than in the 2008 cohort. The 2018 cohort was also characterized by a lower overall adiposity. Regardless of the lower body adiposity percentage, in 2018 there was a tendency towards the central allocation of fat tissue. This is a negative phenomenon because, especially when co-existing with reduced lower-limb adiposity, it is associated with an increased risk of metabolic and cardiovascular diseases, even in young children.
